HULKY BOI REMOTE
Background: Thought about how easy it would be to cram my one a123 cell into my poor- non consenting mini controller.
The picture on the top is a mock-up, and had no real connections as of this morning.
I post this here to show the final result, some recommendations, and to comply with the requests I received 
Let’s be honest, you are probably going to have these parts👇 in one of the many esk8 drawers you have
Parts needed:
-Battery of your choice
-latching switch
-charge port
-thin gauge wire
(And ya remote, duh)
That’s it!
No bms, no resistor, any of that.
Due to lifepo4s low voltage nature, we don’t need a resistor. It rarely will be charged and we aren’t keeping several sets of cells in check… so a balance board is a little overboard.
Use all that real estate for more JUICE.
Recommendations:
-Avoid using the hard plastic wire.
You want flexible wire will all the connections you are going to soldering up in there
-keep all the electronics, along with the trigger section and control board on one side of the remote. This will save you so much headache trying to bridge connections from both sides.
-keep the upgraded switch on the main remote body. Don’t put it where I did.
-and re-solder the connections from the potentiometer to the pads. When disassembling, these can easily be pulled or twisted from the pcb so it’s best to redo them and be confident that it don’t do any wonky stuff on ya.
There are a few simple steps.
1) use a some cutting tool to rip out the battery box and trim cutout to size
2) remove ‘wheel’ plastic nob and potentiometer bracket from the remote, this area is where you will wire in your charge port and switch.
3) sand down the remaining plastic part that would restrict the motion of the plastic wheel you removed. This should leave a nicely sized hole that is perfect for this style charge port
4) make sure your battery fits well in the remote with both sides closed, and solder some wires to the cell once you confirmed a nice fit
5) next, use these long wires from the battery to connect
POSITIVE: (charge port and pcb)
NEGATIVE: (charge port and first input of latching switch.)
6) wire the latching switch output to the pcb (make sure its in the off position)
And TADA, you have yourself a reliable remote that you will have to charge yearly 
Can charge it when it reaches its birthday.
